Once you hit 50mph and let off the gas,the transmission should drop into overdrive from about 2000RPM to about a little under 1500RPM on the tachometer. It actually a little over 1300RPM if your checking from a scan tool. It will increase slightly as you aproach 60mph.
You can kinda feel when the torque converter locks up nothing harsh but....you can feel it.
